It may break $6400 support in few days but whether it will go below $6000 or not is the real question so your predictions is not very useful for me because if it go below $6000 things will change.
Yes currently the selling pressure is increasing, but i think that bitcoin will get a good support at 6000$ and hopefully bitcoin price will not cross that leve so soon, i think once bitcoin price get some support then people will again start investing their money there and hopefully then its price will once again start increasing and will even reach to its previous price in which it was trading a month before.
